The Norse god Odin was willing to sacrifice a lot in the pursuit of knowledge. He exchanged one of his eyes to drink from Mimir’s well of wisdom, for example.
But wait, there’s more…
Among Odin’s many names are God of the Hanged and Hanged One. Óðins Rune Song, a section of Hávamál, details how Odin hung himself from a windy tree for nine nights in order to discover magical runes. During his ordeal, Odin didn’t eat or drink anything, and he suffered from a spear wound besides. The runes gave rise to eighteen different spells.
Times sure have changed.
When I was in college, the getting of wisdom involved hanging out at the library.
